JOHN WILLIAM PIPPIN, OF BROWNWOOD, TEXAS.

OIL-BURNER.

Application filed December 17,1907. Serial No. 406,856.

Speccaton of Letters Patent.

Patented March 16, 1909.

To all whom it may concern: v

Be it known that I, JOHN WILLIAM PIPPIN,

a citizen of the United States, residing atv Fig. 2 is a plan view of the burner. Fig. 3 is a section on the line 3 3 of Fig. 2. Fig. 4 is a section on the line 4-4 of Fig. 2. Fig. 5 is a longitudinal section through the oil heater. Fig. 6 is a vertical section through the cover of the water box and the parts attached.

In' the present embodiment of my invention, the burner is shown applied to a range E, and comprises the burnerAA to be presently described, a water tank or container B, connected to the burner by a flexible tube l), and a fuel supply` tank C, supported by a stand c, and connected tothe burnerby a tube c.

The burner A comprises an oil heater o", a boiler a, a water box a, a steam dome o2 and an atomizer o3.' The box o is provided with covers a4, secured to the box by screws a5, and

one cover has arranged therethrough a nipple a6, provided with a valve seat, in which works a needle valve o7, pivoted to one arm of an elbow lever o8, having its trunnions j ournaled'in a bracket a9 on the inner facey of the cover, and having a llcat am connected with the other arm.

The flexible tube b leading from the water tank B is connected with the nipple, and the flow of water from the tank to the box is controlled by the float uw, the water in the box, and as a consequence the water in the boiler, being retained at a predetermined level.

The water box 0/ communicates with the boiler a by a relatively small water port all, near the bottom of the boiler, and by a relatively large steam port om, near the top of the boiler, as shown in Fig. 3, and the boiler communicates with the steam dome a2, by a ort (1,13 leading from the top of they boiler. Vithin the dome is a pi e a opening near the top of the dome, an extending through the bottom thereof, the outer end being threaded for connnection with the atomizer o3.

The atomizer com rises a pi e L15 extend-'j `mg toward the lire ox e of t e range, and having at its inner end a rsmall opening 0,16. AT, L17 is threaded on the outer end of the pipe (L15, and the lateral branch of the T is' threaded on the lower end of the steam dome pipe (1,14; A short pipe @1 8 is threaded in the outer endA of the T, and a second T, (1,19 isV threaded on the pipe als. y,Axdischarge valvev a2 is connected with the outer end of the T, and a pipe u32 provided with a valve' 01,33 connects the lateral branch of theT with the to of the oil heater o0, tovbe resently describe The pipe 0,18 is of relative y small internal diameter, and a small tube @21 is fastened into the opening, the tube extending to a point adjacent to the opening 'of Y the atomizer. The freeend of the said ytube issupported by a spider o23, and is providediwith a nozzle ai. The atomizer discharges yonto a spreader ai? which is adjustably supported in a pan c25, arranged in the fire box, and provided at its ends with brackets @31, upon Which'the boiler is supported. An'oil leader a26 is adjustably connected with the end of the atomizer pipe by a set screwow, and assists in directing the spray of oil` against the spreader. The spreader is slidable in the pan and may be moved from' one end to the other being sup-VL i ported on ledges a,X as shown in Fig. 2.

The oil heater o", comprises a cylindrical casing, connected-onits bottom side with a tube c communicating with the tube c,

which communicates with the oil tank C, the' pipe L32 before mentioned leading from the top side of the casing. By'means of the valve (L33, the supply of oil to the atomizer may be regulated, and as a kconsequence the intensity of the fire.

A pop-off valve (L28, is arranged adjacent to the steam dome and communicates with the bottom thereof, as at o2", and apipe e30 leads from the pop-off valve tov and through the oil heater o and into a drain pipe u32., The drain pipe (1,32 leads from the pan c25,

opening above thel bottomffthereof, and is adapted to carry away any excess of oil in the pan.V The pop-orf valve may be adjusted to any predetermined pressure, and carries oi the excess and wet steam passing it through the heater and warming the oil therein so that it becomes thin and light, and in excellent condition for atomizing.

A valve a34 is arranged between the water tank and the water box, and a drain valve m35 is connected with the water box. By means of these valves, the water may be cut off from the boiler and box, and they may be:

drained to prevent freezing. The valve at the outer end of the atomizer pipe permits cleaning of the atomizer tube, should for any reason said tubebecome choked. The removable cover or head of the water box is provided with a glass covered peep-hole az, and the arm of the elbow lever is threaded so that thekloat may be adjusted, to maintain the water at different levels.

The oil tank may be arranged at any suitable point, usually outside of the house, but the water tank should be inside. Said tank is shown supported by a cord b connected with the tank and passing over a pulley b2, secured to the ceiling, so that the tank may be raised or lowered to insure a water pressure in the water box greater than the steam pressure.

In o eration, the tanks being supplied with oil an water respectively, oil is admitted to the pan and ignited. The heat will soon generate steam which willpass into the steam dome, from whence the dry steam passes to the atomizer, spraying the oil from the heater onto the s reader. The excess steam passes through t e heater, heating the oil therein, in its passage, and discharges through the discharge pipe.

It will be evident from the description that the oil, steam and water are each automatically controlled, so that enough of each is supplied to insure a erfect combustion with no soot, odor or smo re. Either light or heavy grades of oil may be made use of.

It wi l be evident from the description that the steam is delivered to the atomizer at a steady and predetermined pressure, and that the excess steam above the pressure is utilized to heat the oil previous to its entrance into the atomizer.

I claiml. An oil burner comprising a water box, means for supplying water to the box, a loat valve in the box for controlling the supply, a boiler having a lower relatively small water port and an upper relatively large steam port communicating with the water box, a steam dome, communicating with the top of the boiler, a vertical pipe in the steam dome, said pipe opening near the top of the dome,

and extending through the bottom thereof, a pan below the boiler, a spreader in the pan, an atomizer connected with the steam dome pi e and discharging onto the spreader, an oi heater communicating with the atomizer, means for supplying oil thereto, a waste pipe leading from the pan, a pop-0H valve in connection with the steam dome, and a pipe leading from the pop-off valve through the oil heater and into the waste pipe.

2. An oil burner, comprising a boiler, means for supplying water to the boiler, means for retaining the water in the boiler at a predetermined level, a steam dome, with which the upper part of the boiler communicates, a vertical pipe in the steam dome, said pipe opening near the top and extending through the bottom of the dome, a pan below the boiler, a spreader in the pan, an atomizer connected with the steam dome pipe and discharging onto the spreader, an oil heater communicating with the atomizer, means for supplying oil thereto, a waste pipe leading from the pan, a pop-ofi valve in connection with the steam dome, and a pipe leading from the pop-oilLl valve through the oil heater and into the 'waste pipe.

3.

5. An oil burner comprising a boiler, a spreader below the boiler, an atomizer, means for conducting steam from the boiler to the atomizer, a spreader below the boiler onto which the atomizer discharges, an oil heater delivering to the atomizer, a safety valve in connection with the boiler, and means for receiving the excess steam from the valve and passing it through the heater.

6. An oil burner comprising a boiler, an atomizer, discharging below the boiler, means for conducting steam from the boiler to the atomizer, an oil heater delivering to the atomizer, a safety Valve in connection With the boiler, and means for receiving the excess steam from the valve and passing it through 5 the heater.
